Answer this !!

[victor]

Hi, it’s me E.anythingus…as a soon-to-be-microbiologist, I wanna held a test for all of you..huahahaha..enjoy it..it’s about virology. Don’t cheat dear.. 😆
give a brief explaination of: (V = virus)
EBV, HIV, CMV, SIV, ArboV, MyxoV, RetroV, PaPoVa-V.

[MrMistery]

What’s in it for me?

[Squawkbox]

is it the 22nd letter in a geek childs alphabet wall chart:?:
A=anatomy
B=bacteria
C=clostridium
D=diaphragm
E=E. Coli
etc etc etc
V=virus
etc etc etc

[mith]

lol I only know retro, uses rna template to convert to dna

[canalon]

EBV=Epstein-Barr Virus cause Infectious Mononucleosis
HIV= Human Immunodeficiency Virus cause AIDS
CMV= Cytomegalo Virus, no idea what it does 🙂
SIV= Simian Immunodeficiency Virus cause AIDS in apes
ArboV= ArboVirus or viridae, a family of virus
MyxoV= Myxovirus another family
RetroV= Retrovirus…
PaPoVaV=No idea

Without even googling…

[jnkdna]

i dont know any except for human immuno deficiency virus!!!!

[victor]

PaPoVaV=No idea

Wow..cool !!!
by the way, PaPoVa virus consists of three viruses.. 😆
it’s Human Papilloma Virus, Rabbit Polyoma Virus and Simian Vacuolating agent..tricky eh?? 😆

HEy, you need to learna few things before being Dr Canalon 😉
But can you explain us why the PaPoVa are grouped together?

[opuntia]

Do they all cause the same disease? 😕 😕

[jnkdna]

i dont think they all cause the same disease but im pretty sure they are all connected some how!
but then again it makes more sense if they cause the same disease. y else would they be grouped together!!

it’s because three of them (like previously said by Opuntia) make the same dissease which is "crabs"… 😆

Oh, forgot something Doc…Cytomegalo virus is just like the name causing Cytomegalic condition inside the cell…

[opuntia]

And "crabs" mean cancer?

[Dr.Stein]

quote opuntia:

And “crabs” mean cancer?

😆 I already know this joke but I still can’t stop laughing everytime I remember 😆

I think I came late to the test, means that I do not necessary to do them eh? 🙂

[opuntia]

Since you are too late that means you won’t get any marks, right, Sir Victor? 😆

[victor]

Okay..I’ll give the late person a makeup test… 😆
which of these virus family that cause dissease named chicken pox??
a. Hepadnaviridae
b. Retroviridae
c. Herpesviridae
d. Poxviridae
e. Adenoviridae

[opuntia]

c is the correct answer!

[victor]

Yo…you’re right fella…:lol:
and now, for a lil bit hard one..
HIV have a +sense RNA that can act as mRNA for protein translation…but in the replication process, it doesn’t do that…explain why and describe the pathway it use..

[opuntia]

That’s too tough for me…coz i haven’t studied that yet, so i give up for now but will come up with the answer when i learn them 😀

PS: has it got anything to with the virus having reverse transcriptase?

[victor]

actually you can answer it…just see the picture of HIV in my signature…it helps you a lot…
a clue: +sense RNA virus that use it’s RNA as mRNA can be classifid into ssRNA (single stranded RNA, or in other words, haploid RNA)…happy answering..:lol:

[Nite]

ds DNA is formed from the +RNA by reverse transcriptase. The ds DNA is then incorporated into the host chromosomal DNA and the virus enters lysogeny cycle.

It’s a characteristic of retrovirus as u mention before?

why it does so? guess it does that so that it can be incorporated into the host DNA?

hehe. i just had a lecture about HIV today 😀 .
i m a newbie in virology 😳

btw, wad does GAG and GP in the HIV diagram stand for?

[victor]

Yup, that’s the "common" characteristics of retroviruses….why I call it common??because there’re three subfamilies of retroviruses: Oncovirus, Lentivirus and …..virus..(argh, I forgot the name)..poor me.. 🙁
Why it does so? because according to Baltimore virus’ classification, retroviridae is classified into dsRNA with DNA intermediate (reverse transcriptase) which has a diploid RNA attached to reverse transcriptase enzyme for each of them….and also, in order to do capsid "uncoating", they have to do so..
gag is a code for virion’s protein construction.
gp = glycoprotein… 😆 so, gp120 = glycoprotein code 120…
easy isn’t it.. 😆
don’t say like that Nite, because I’m also a newbie in Virology and now, I’m learning for the next virus which is Herpesvirus.. 😀

[victor]

And now, for the next question..:lol:
I’ve just read about EBV or in other words every body’s virus..:lol: (it’s real name).
Now, if EBV crates Lymphoblastoma on B-cell and affecting of excesses IgM antibody secretion, then why it’s said than EBV is harmful for us?? more antibody is better isn’t it??:lol:

[Dr.Stein]

Naah. The excessive IgM and IgG is because of the excessive VCA/EBV/EBNA. You know the immune response… If you want to get those immunoglobulins for more, ok ok I will inject you with more EBV, agree? 😆 Maybe you want to experience how is the feeling of suffering mononucleosis, Burkitt’s lymphoma and nasopharyngeal carcinoma. Come to me my dear, I still have some vials of EBV mwahahahaa 😈 😆

[victor]

the answer is excessive on IgM can cause erythrocyte aglutination..hahaha..and beside, the infected B-cell secretes an IL-10 like protein that cause inhibition of IFN-gamma secreation in T-cell and NK-cell..

a. Hepadnaviridae
b. Retroviridae
c. Herpesviridae
d. Poxviridae
e. Adenoviridae

C is the correct answer. The varicella-zoster virus to be exact one of 8 herpes virus I think.

[victor]

Ok, let’s head for the next question: 😆
how many classification based on virus’ capsid structures??

[Dr.Stein]

*yaaawn* 😳

[victor]

why boss? you look so sleepy in this question??:lol: is it because you’ve just come back from Jakarta…:lol:

[Dr.Stein]

Hehe you know that 😳 😉 I visited Mr.Stein 😛
I remember a subject in our faculty: Systematics of Microbes, I am sure you will take it when your time comes 😉

[victor]

Unfortunately…you guess it wrong boss…I don’t really like taxonomy..
Ok, the answer is:
there are 3 types which are symetry icosahedral, sphrical and complex structure…:lol:

[Dr.Stein]

You should know that there is a principle difference between "systematics" and "taxonomy" 😉 You will see the difference soon 🙂

[victor]

I hope I can pass it with a good score…:lol:
Next:
Based on those three types of virus structure, now what structure that TMV and bacteriophage bears??

[damien james]

Victor, you’re going to be a microbiologist too? Cool! I graduate this year with degree in microbio, but only undergrad :(. Do you know where you’re going to work yet?

[victor]

@Damien james
I think it’s more proper if we bring this chat into PM…just PM me okay..:D
ok, continue to the topic, what’s the answer guys?? 😆

[JimmyC]

Dear Victor, I’m pretty sure your little quote is bollocks as in an endothermic reaction u could just put more heat in or maybe if there are less moles of product produced than reactants put in then u could also up the pressure to get a higher yield!

[opuntia]

quote victor:

I hope I can pass it with a good score…:lol:
Next:
Based on those three types of virus structure, now what structure that TMV and bacteriophage bears??

Am i late for the class? i hope not
TMV=Spherical
Bacteriophage=Icosahedral

Not so sure about the phage…could be because i always hate microbiology so very much! 😆 😆

[victor]

They’re complex…:lol:
Hey, this post has overdrowned I think.. 😆

[opuntia]

Yeah, I’m trying to bring this alive again coz next semester i’ll be studying microbiology and i’m a real dope at it.

[victor]

Hmm..I can think that MicBio is very interesting…because it’s a chance in a lifetime you’re given to observe thos tini creatures… 😆
